CONCRETE SEWER CONSTRUCTION.

To all whom it may concern:

Be it known that I, BURTON LowrHER, a citizenof the United States, residing at Kansas City, in the county of Jackson and State.

of Missouri, have'invented certain new and useful Improvements in Concrete Sewer Cons ruction, of which the following. 1s a specifi;

`^ ject is to produce a simple, strong,'durable and comparatively inexpensive construction of thetype mentioned expeditiously and at a minimum expense.

To this end the invention consists in lcertain .novel and peculiar features of construction and organization as hereinafter described and claimed; and vin, order that it may be fully understood reference is to be had to the accompanying drawing, in whichz` Figure 1, isan end view, of a section of sewer construction embodying my inven- Yyond the upper edge of the section and bent back at itsends to form loops or eyes 5. Eachsection is also provided with longitudinal reinforce rods 6 in the planes of grooves 3, the rod 6 of each section being sufliciently long to' project into the registering grooveA 3 of the adjacent sections and-terminating inA hooks 7 which referably are disposed substantially'radia ly of the section, the said hooks being disposed inwardly by preference.

8 indicates the side sections, the same being arranged edgewise together with their lower ends resting upon the invert sections, it being.

further noticed that the sections 8 break joint with sections 1. Sections 8 at their inner lowercorners are VSpecification of Letters Patent.

-Application filed March 3,

Patented June'e, 190s. 190s. serial No. 419,053.

Iprovided withlongitudinal grooves?) opening 'into grooves 2 and v.at their side edges and outer sides are provided with grooves 10, the upper ends of grooves 10 communicating with grooves 11. in the upper, outer corners of said sections, the grooves 11 extending parallel with the similar grooves 9 hereinbefore described.

The sections 8 are reinforced by a plurality of rods 12 paralleling grooves 9 and 11 and arranged in the planes of grooves 10, and of such length as to project into the proximate grooves 10 of the adjacent sections, the ends of said rods terminating in outwardly -projecting hooks 13, it being further noticed in this Aconnection that by this arrangement vthe hooks 13 of thelower series of adjacent rods 12, project outwardly at opposite sides of the lupper ends of reinforce rods 4. 14 indicate cap sections.v connecting and vsupported by the opposite sections 8, and provided in their outer corners with grooves 1 5 parallel and communicating with grooves 11 of sections 8, and also provided with transf verse grooves 16 connecting the transverse grooves 10 of sections 8. c

17 are parallel reinforce rods extending through sections M in the planes of grooves 16 and provided like rods 12, with outwardly 'projecting hooks 18 to occupy the grooves 1.6

of the contiguous sections 14.

19 indicates reinforce rods occupying the `transverse grooves formed by grooves 10 and 16 and fitting against rods 12 and 17 between the outwardly projecting hooks 1 8 and '18 thereof, the lower ends of rods 1 9 terminating in loops 20 engaging the eyes 5 of rods 4.

,To 'bond the sections permanently together as a monolith the communicating grooves 2 and 3 are filled with cement, grout or an equivalent binder, it being )referred, however, to reinforce this bin ing material by first securing U-shaped reinforce bars 21 in the grooves 3 .and betwee the hooks 7 of adjacent rods 6.

`The grooves formed by the communicating grooves 11 and 15 and the grooves formed by the communicating grooves 10 and 16, are also'iilled with a similar or equivalent binder. i

.When the binder material is set the sections are bound irrevocably together, it being obvious that unskilled labor can be..

,utiied in constructing the sewer and thet- .zidity l From the above )description it will be 'apparent 'that Ii have produced a sewer embodying theA advantages enumeratedas desirable andV whicli is obviously susceptible of modification as regards its form,

the "joik` can be carried on with great raproportioin, detail construction and ar-v rangement without departing 'from the principle and scope of the appended claims.

Havin thus described the invention, what I caim as new and desire to secure by? Letters Patent, is,'-
